A brief investigation into allegations of hazing within Florida State University fraternity Alpha Phi Alpha found the claims were unsubstantiated.

FSU officials confirmed they have closed the investigation into the allegations against Alpha Phi Alpha

Last week, the Iota Delta chapter was issued a cease and desist letter, barring the group from meeting or conducting other activities.

The allegations of physical and mental abuse stemmed from an email a pledge sent to FSU administrators, Alpha Phi Alpha officials and media detailing the accusations and showing a video of an interview being conducted by investigators via computer.

A letter from FSU Associate Dean of Students Alan Acosta to fraternity President Jeffery Hardy indicated the investigation was closed and the fraternity would be able to return to its normal activities.

“I have reviewed updated information from the Florida State University Police Department regarding recent allegations of hazing,” Acosta wrote in the April 13 letter. “The Dean of Student Department has determined there is a lack of evidence to substantiate continuing the interim disciplinary action.”
